st: How to test the equality of marginal effects after running probit, oprobit or mprobit models |

Dear all, I would appreciate your response to the following questions: 1) I randomized my sample into 5 groups and now I want to test if the sample is balanced for my independent variable (which is binary). I run probit model and get the marginal effects for the treatment dummies but when I run the –test- command, it seems to be testing the equality of log odds ratio and not the marginal effects. How do I test the equality of marginal effects? 2) To see if the sample is balanced for independent variables which have multiple categories, I run –oprobit- or –mprobit- commands and get the marginal effects for each category by using predict(outcome(x)) option. But then again, how do I test for the equality of marginal effects for each outcome? Many thanks.
